About this study:

Few robust quantitative data on the magnitude and impact of disability on people’s lives are available globally, and amongst the limited evidence base that exists, different methodologies used in defining disability make comparison between countries and over time extremely difficult.

Collection of comparable disability data is advocated by WHO World Report on Disability and a key component of ongoing Post 2015 debates. This study set out to develop a comprehensive population-based disability survey methodology that was compatible with the ICF, and to explore the relationship between components of the framework.

This methodology was field-tested in Telangana State, India and North West Region, Cameroon between 2013-2014.

“We always struggle to have reliable data on disability which is very much needed to inform our work. This comprehensive assessment tool helps us and others in gaining such data while also relating to the life realities behind the ‘figures’.”  says Christiane Noe, CBM Research Manager.
